A government report commissioned by Innovate UK, along with the UK Space Agency and the Royal Institute of Navigation, entitled “Economic impact to the UK of a disruption to GNSS”, comes in the wake of troubling incidents for GNSS operators, both the United States and Europe.
Last year a problem with the GPS satellite timing signal triggered alarms and caused an unknown number of outages, and in Europe earlier this year the fledgling Galileo signal crashed due to unspecified ground facility issues.
